## Definition

## Cosmetic efficacy and claims
Efficacy and claims work connects a proposed product benefit with an appropriate study and proportionate wording. Human observations, instrumental measurements, consumer perceptions and laboratory mechanisms provide different evidence and should remain distinguishable.

### Efficacy and measurement
[Cosmetic efficacy testing](https://cosmetic-labs.com/services/clinical/efficacy) investigates defined product benefits. [Instrumental and biophysical testing](https://cosmetic-labs.com/services/clinical/efficacy-testing) quantifies selected properties or responses using a method suited to the question. The tested model, site, comparator and use conditions determine the scope of the result.

### Consumer experience
[Consumer sensory testing](https://cosmetic-labs.com/services/clinical/consumer) captures application attributes, acceptability and perceived benefit. Descriptive panels, home-use trials and surveys have different purposes and cannot supply missing objective efficacy evidence.

### Claims substantiation
[Claims substantiation](https://cosmetic-labs.com/services/clinical/claims) includes evidence planning, study documentation and review of marketing statements. Planning and review are iterative, and records develop throughout the work. Safety review is a prerequisite for appropriate human exposure but is a separate service scope, not one of this hub's four branches.

## Applications

## Match the evidence to the benefit
Cosmetic efficacy testing examines defined product outcomes. Instrumental and biophysical measurements quantify selected physical properties, while consumer sensory studies capture experience and perception. A programme can combine them, but subjective and objective findings should remain identifiable.

Claims substantiation begins with the proposed wording and available evidence. Planning, documentation and marketing review help identify gaps and keep conclusions within the tested population and conditions.

There is no universal pipeline in which all documentation comes last. Safety and ethical review are prerequisites for appropriate human exposure and are separate from this efficacy-and-claims category. Study records and evidence review should be maintained as results emerge.
